editor: add word wrap toggle to status bar

Adds a "Wrap" button to the editor status bar that toggles word wrap
on/off, persisted in localStorage. Default is nowrap with horizontal
scroll (standard code editor behaviour). In wrap mode the line-number
gutter and current-line highlight are hidden — both rely on fixed
line-height calculations that break when lines wrap visually.

CSS: textarea/overlay default to white-space:pre; .vv-ed-wrap class
(on #vv-editor-wrap) overrides to pre-wrap, hides gutter and cur-line.
JS: vvWordWrap state, vvApplyWordWrap(), vvToggleWordWrap(); guards in
vvUpdateLineNums() and vvUpdateCurLine(); restored via
vvRestoreEditorPrefs() on both script and raw-conf editor entry points.
